A solution of 690 mg (1.64 mmol) of the compound from Example 98A in 10 ml of THF was added dropwise to 5.8 ml (5.75 mmol) of a 1N lithium aluminum hydride solution in THF under argon in 20 ml of THF at RT. 1N hydrochloric acid was then added, the mixture was extracted with ethyl acetate, and the organic phase was dried over magnesium sulfate, filtered and concentrated. The crude product was purified by preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% formic acid) to result in 0.60 g (97% of theory) of the title compound.
